An apparatus (10) for delivering a grinding media from a holding vessel or storage vessel to a grinding mill, the vessel holding a quantity of the grinding media, the grinding media being in the form of a particulate material, the vessel having an outlet at lower end. The apparatus (10) comprises a housing (12) positioned below the outlet of the vessel, the housing (12) receiving grinding media from the vessel, a nozzle (80) delivering a liquid to the housing, and a mixing chamber (110) having an inlet for receiving liquid and grinding media. The inlet of the mixing chamber (110) is spaced from an outlet of the nozzle (80) whereby liquid exiting the nozzle (80) entrains grinding media in the housing (12) and a mixture of liquid and grinding media enters the inlet of the mixing chamber (110) and is further mixed in the mixing chamber. The mixing chamber has an outlet through which the mixture passes into a diffuser (130) and then on to a pump box of a grinding mill. The mixture may be dewatered prior to passing to the pump box. |
